Definitions

  • a paper producing system it is known to dispose a plurality of strips, offset from one another in the direction of motion of the screen belt, on the underside of that screen.
  • the purpose of the strips is on the one hand to scrape off the water that escapes from the pulp and passes through the screen.
  • the strips create an air compression on their front ends (in terms of the direction of motion of the screen belt), which induces turbulence in fibers of the pulp, which in turn changes the structure of the paper or improves the quality of the resultant paper.
  • the grooves extending at an incline relative to the direction of motion of the carriage by an angle of substantially between 0.5° and 5°.
  • the invention provides for a carriage to be disposed between the guide rail and a nondisplaceable support for the strip.
  • the support for the strip is embodied with grooves on both its side faces, into which grooves guide elements, in particular bearing balls, provided in the carriage protrude.
  • the grooves are inclined relative to the direction of motion of the carriage (i.e. the longitudinal axis of the frame-fixed guide rail) by an angle of between 0.5° and 5°.
  • the grooves of suitable incline are provided in the carriage.
  • the guide elements such as bearing balls for instance, are provided in the support.
  • a major advantage of the afore-described invention is found in the fact that the strip need not be displaced relative to the screen belt. Accordingly, it suffices for its length to be equal to the width of the screen belt, which minimizes the expense in terms of material and production. Moreover, the components that are used to adjust the height or angular position of the strip can be provided with a cover, so that effective and complete protection against the intrusion of water can be attained.
  • the angle of inclination of the particular groove that is located on the side toward the front edge of the strip is smaller than the angle of inclination of the particular groove that is located on the side remote from the front edge.
  • FIG. 6 is a cross-sectional view taken along the line VI--VI of FIG. 4a;
  • FIG. 7 is a partial view of the cross-section of FIG. 1 showing an alternative embodiment.
  • the grooves 34, 34a provided in the first part 31 of the support 3 form an angle of approximately 3° (between 0.5° and 5°) relative to the direction of motion of the carriage 2 (the longitudinal axis of the fixed guide rail 1).
  • an actuator 7 is associated with the guide rail 1; it comprises a hand crank 71 and an adjusting spindle 72 supported in threaded fashion in the guide rail 1.
  • the carriage 2 is coupled in a slaved relationship to the free end of the adjusting spindle 72 by means of a disk 73.
  • the actuator 7 is also embodied with a measuring scale 74.
  • the height of the strip 4 can thus be adjusted precisely, in a simple way.
  • the grooves 34 and 34a in a second embodiment by comparison extend at different angles relative to the direction of motion of the carriage 2; the angle of the grooves 34 located closer to the front edge 45 of the strip 4 is smaller than the angle of the grooves 34a facing toward the rear edge thereof.
  • FIG. 2 shows a pivoted position of the strip 4, which is brought about by a displacement of the carriage 2 if the grooves 34 and 34a are inclined differently from one another.
  • a wedge-shaped gap 40 is formed between the underside of the screen 5 and the top 46 of the strip 4.
  • the balls of the ball bearing are alternatively placed in the support 3 and they roll in groove slots formed in the carrier 2.
